Poultry farming is the one of the rapidly developing sector that plays an important role in food and nutritional security worldwide. Indian poultry industry is a fast growing sector constitutes an important component of the agricultural economy of the nation. India is third largest producer of eggs and fifth largest producer of poultry meat in the world. Poultry production in India has become increasingly specialized and integrated into a dynamic industry of National and International importance. Poultry farming is also growing very fast in Tamil Nadu in terms of both layer and broiler production.
Namakkal is the most densely populated layer producing region in India and occupying first place in egg production at National level. The Namakkal zone has a layer poultry population of approximately 50 million which produce nearly 40 million eggs per day. The 90% of egg export of India is originating from Namakkal. Broiler industry is growing well in neighboring districts of Namakkal mainly Tiruppur and Coimbatore districts of Tamil Nadu where the grant parent, parent and commercial broilers are reared. The broiler chicks and hatching eggs are sold to different part of India and also exported to foreign countries.
To sustain the poultry industry in this area, Tamil Nadu Agricultural University (TNAU), Coimbatore established a center called Poultry Research cum Investigation center on 04.09.1979. It became one of the constituent units of Tamil Nadu Veterinary and Animal Sciences University (TANUVAS) when it was bifurcated from TNAU on 20. 09. 1989. To cater the increasing demand of poultry farmers, the laboratory further started disease surveillance activities and renamed as Poultry Disease Diagnosis and Surveillance Laboratory (PDDSL) on 01.12.2010 by TANUVAS.
At present, the PDDSL, Namakkal involving in the diagnosis of the existing and emerging diseases by providing post mortem service, isolation and identification of causative organisms, serological tests such as HA, HI, ELISA and molecular diagnostic test like PCR. To create awareness among the poultry farmers on poultry diseases and management, this laboratory is regularly conducting technical meet and training programmes. Apart from that weekly poultry disease forecasting is regularly carried out through newspapers for the benefit of poultry industry.


OBJECTIVES

  • Post-mortem examination and laboratory diagnosis of diseases.
  • Seromonitoring of Newcastle disease and Infections Bronchitis viral infections in poultry.
  • Surveillance of common diseases prevailing in commercial poultry farms.
  • Screening of Salmonella of zoonotic importance in poultry and related products.
  • Monitoring the health management in commercial poultry farms.
  • To aid in the post graduate research in poultry disease management.

Infrastructure

The laboratory is mainly concern with the diagnosis and control of poultry diseases and has well equipped bacteriology, virology, serology and molecular diagnostic units.

Salient achievements

  • A self-financing scheme on “Holistic health management in commercial poultry through diagnostic, preventive and biosecurity interventions” is implemented for the benefit of the poultry farmers of Namakkal region.
  • Filter paper techniques for collection of blood serum for estimating the antibody titre for ND and IB is being adopted routinely at PDDSL, Namakkal.
  • Screening of Avian Influenza (AI) test by RT-PCR on clinical samples sent through AQCS, Chennai for the purpose of egg export.
  • A technique on use of trypsin enzyme for activation of IB virus for conducting HI test.
  • A laboratory for screening of Salmonella of host specific and of zoonotic importance was established. Serotypes such as Salmonella Newport, Salmonella Enteritidis and Salmonella Typhimurium was identified from poultry and poultry related products.
  • A rapid multiplex molecular diagnostic tool was developed for the detection of Salmonella organisms in poultry and its related products.
  • A molecular diagnostic laboratory was created for detection of economically important poultry diseases.
